# AWS publishes an EKS guide to multi-node Ray LLM inference

> An AWS guide dated October 12 demonstrates a Ray LLM container setup on EKS that splits one LLM across two GPU nodes, running prefill and token generation separately. The post focuses on deployment and configuration.

AWS published a technical walkthrough for serving one large language model across two GPU nodes on Amazon EKS with the Ray LLM Deep Learning Container. In the example, one node runs prefill, which processes the prompt, and the other runs decode, which generates the response token by token; NIXL transfers the key-value cache over EFA.

The guide uses Ray Serve LLM and YAML configuration for a tested GPU software stack behind one OpenAI-compatible endpoint. It reports reducing Qwen3.5-9B model-weight loading after restart from about 145 seconds to about 2 seconds; that figure depends on the example’s cache settings and g6.8xlarge setup. The post is a deployment walkthrough, not an independent comparative evaluation.
